Phosphate ion, phosphoric acid occurrence, compounds, identification, reactions . The main source of phosphorous is apatite. Phosphoric acid (H 3 PO 4) is a weak acid. In many occasions phosphate ion give coloured precipitates. Phosphate ions are very important in fertilizing industry. Molecule of phosphate ion(PO 4 3-)
A circulating process of no draining waste is disclosed. The bothering difficulties of separation and pollution problems in the current hydrochloric acid process of phosphorus rock are thus overcome. By the principle of cooperative effect of HCl, calcium chlorophosphate and calcium chloride can be crystallized separately from the different zones of phase diagram, thus solid calcium ...
Mar 21, 2019· If you just want to see how much calcium phosphate 'disappears' into a hydrochloride acid, the answer is to: 1. measure some HCl, (volume ), to be easy choose 1 litre. 2. Weigh the beaker and acid. 3. Add calcium phosphate slowly, stirring well, u...
